The XEL40xx Series of low-loss power inductors

The XEL40xx Series of low-loss power inductors released by Coilcraft comes with lower inductance values that have been fully optimized for high frequency applications.

They also offer extremely low DCR (as low as 2.5 mOhms) and ultra-low AC losses, resulting in the highest efficiency across a range of frequencies (2 to over 5MHz). They are offered with current ratings as high as 28.5 Amps, and their soft saturation characteristics can withstand high current spikes.
